Long charge time
First I want to thank Roy, Mex, Piano and others for posting good electrical info on here. I have now installed a PD4655 converter, 4 new 6 volts, 6 gauge wire from converter to batteries and batter...

If you pull wire use the #2. You can step down the #2 TO #4 for the last 12" at the converter. Upgrade the entire loop including ground at the converter and battery.
If instead you pull 120v wire I would probably stick with PD brand and put a PD9280 near the battery. (20a circuit required) If you want real temperature compensated 14.8 volts you may need to step into Xantrex, Mastervolt, or Victron battery charger and the price goes up substantially.
Trouble with Powermax is that it does not hold 14.6 volts. Powermax immediately trips down to 13.6 volts once you hit that trigger. Very close to the battery with #2 will delay the trigger long enough it may work for you and your PD4655 could take over at that point. IOTA only holds 14.6 for 15 minutes before dropping to 14.2 for an extended period (8 hrs?) before dropping to 13.5 volts.
No need to pull both 12v & 120v wire.
